Conda Pack

摘要:

移植python环境一般用于以下两种情况：

1. 别人要运行你的代码，但是没有你的python环境，如果要一个一个python包进行安装，则非常麻烦，并且有时候还安装出现问题。
2. 有一个包始终安装不上，但是在你的另一个python环境下有，或者在别人的环境中存在，这个时候就可以将python环境打包，移植到你的电脑上，然后激活该环境，运行对应的项目。

安装Conda-Pack

在打包之前如果没有conda-pack包的话，需要安装pip install conda-pack

进行python环境打包

conda info -e
# conda environments:
#
base                  *  /miniconda38
IMavatar                 /miniconda38/envs/IMavatar
IMavatar_v2              /miniconda38/envs/IMavatar_v2
deca-env                 /miniconda38/envs/deca-env
flare                    /miniconda38/envs/flare
flare2                   /miniconda38/envs/flare2

conda pack -n $环境名字 -o $压缩包名字.tar.gz

# 运行时样例
Collecting packages...
Packing environment at '/miniconda38/envs/deca-env' to 'deca-env--imavatar-data-prepro-env.tar.gz'
[##################################      ] | 87% Completed |  2min 19.6s

接下来，传输这个压缩文件  $压缩包.tar.gz 到你所需要的服务器，并放到anaconda目录的envs文件夹路径下。

# 解压这个conda pack的环境
tar -zxvf $压缩包.tar.gz -C $环境名字
# 实例
mkdir /miniconda38/envs/nha
tar -zxvf nha.tar.gz -C /miniconda38/envs/nha

 注意 

conda pack方法无法跨操作系统进行环境迁移。只能linux到linux，windows到windows，mac到mac。

报错调试

包不一致

ollecting packages...
CondaPackError: 
Files managed by conda were found to have been deleted/overwritten in the
following packages:

- pyyaml 6.0:
    lib/python3.7/site-packages/PyYAML-6.0-py3.7-linux-x86_64.egg-info/PKG-INFO
    lib/python3.7/site-packages/PyYAML-6.0-py3.7-linux-x86_64.egg-info/SOURCES.txt
    lib/python3.7/site-packages/PyYAML-6.0-py3.7-linux-x86_64.egg-info/dependency_links.txt
    + 5 others

    lib/python3.7/site-packages/dataclasses-0.8.dist-info/INSTALLER

    lib/python3.7/site-packages/torch-1.7.0-py3.7.egg-info/dependency_links.txt
    + 3 others

This is usually due to `pip` uninstalling or clobbering conda managed files,
resulting in an inconsistent environment. Please check your environment for
conda/pip conflicts using `conda list`, and fix the environment by ensuring
only one version of each package is installed (conda preferred).

首先，进入你想要打包的那个环境，运行以下命令：

conda list

之后再进行pack，这个报错自己就消失了

报错信息

Collecting packages...
CondaPackError: Cannot pack an environment with editable packages
installed (e.g. from `python setup.py develop` or
 `pip install -e`). Editable packages found:

- /data/lijiawei421/eskandar/projects/3Drecon/point_avatar_deps/pytorch3d

pack方式变动

conda pack -n point-avatar -o pointavatar.tar.gz --ignore-editable-packages

解压缩使用

mkdir ~/ananconda/envs/point-avatar
tar -xf pointavatar.tar.gz -C ~/ananconda/envs/point-avatar
cd ~/ananconda/envs/point-avatar
source ./bin/activate
